IMPROVEMENT IN WASH-BOILERS.

The Schedule referredJo-n these Letters Patent and making part of thesame.

'ence being had to the accompanying'drawings, and tol the letters ofreference marked thereon'.

lIhe nature of my invention consists in the construction and generalarrangement of aboiler, suitable for washing clothes, aswell as forboiling and washing vege- In lorder to enable othersskilled inthe art towhich my invention appertains, to make and use the same, IY

will now proceed to describe its construction and operation, referringto the annexed drawings, which form a part of this specification, and inwhichl vFigure l is aside elevation, in section, ofthe boiler complete,and

FigureZ is a side elevation, in section, of the reversed bottom.` Y A Arepresents a common boiler, with a sunken bottom, although it may bemade of any shape desired.

Inside of this boiler l place another boiler-bottom, B, turnedupsidedown, which reversedbottom has a metal rim, C, put on the flange,projecting downwards any desired distance, and which rim is providedwith a small iiange, a, around its lower edge.

The reversed bottom B, thus constructed*7 rests on that part of thebottom of the boiler A which is not turned down, as shown in iig. 1, andis secured to the same by means of two lugs, b b, in the boiler lA. Asmall slot in the flange a. allows said iiange to be put under one ofthese lugs, and the other extending up through the slot mentioned. Bythen turning the bottom, B, a little, the lugs l1 b will hook the flangea, and hold the reversed bottom tightly.

When the pressure of steam comes on the reversed 'bottom these lugs willhold the ybottom just as firm,

with all the strain there will ever be on it," as though it weresoldered fast. i

.The rim C is provided with'one or more holes, which .are covered withvalves D D, on the inside, so that when the pressure oi' water on theoutside is greater than the resistance oi' the pressure on the inside,after or more notches, and 'on the. bottom, B, is placed a correspondingnumber of lugs or keys, d d. By placing the tube E so that each key fitsinto its notch on the vflange c, and then slightly turning the tube,said keys catch on `the ange and hold the'tube firmly.

The upper smaller end of the tube E is also provided with a flange, c,which is grooved on its under side, and on this iiange a cap,vF, isplaced, which cap, being provided with two or more pins, fj, bent andfitting into the groove on the iiange e, i'oims a loose joint. The upperend of the cap, F, is secured to the horizontal pipe G, one or both endsof which` may be loose, so as to allow contraction or expansion at will.The ends of the pipe G are closed, and from the side near the ends arespouts, H H, through which the hot water will pass out. 4

When the steam and water are forced outthrough the horizontal pipe G andspouts H H, the reaction of the water causes the pipe G to turn in theopposite direction from which the water comes out of the pipes, of

its own accord.

its outer periphery it is provided witha series oismaller circular holesto allow the water to pass through.

Through the cent1-e of the reversed bottom, B, I place a partition orwall, J, which partition extends down wardsfrom the centre oi' the topof said bottom, and is provided at its upper end with a hinged pallet orvalve, L, extending upwards in the tube lil. rlhis pallet or valve is oisuch a shape that, when turned to either side, it will eiiectuallyyclose that side of the tube.

Vhen the reversed bottom, B, is fastened tight to the bottom of theboiler, the partition J should be so 'ar ranged as to iittight allaround, and ii' the boiler has a snnke'n bottom, the partition will godown into it, as shown in g. 2, and fit tight.

When, now, the water in one side of the` boiler gets hot enough tostart, the irst thing it will do will b e to close the valve D,'thenthere is no escape only as it goesup the pipe E, and in order to get upthis pipe it has to throw the pallet L overto the opposite side, thuspreventing the water and steam from going over into the other side.VWhile the iirst side is running, the water has free access to the otherside, through its valve D, and immediately fills, and as soon as thewater is thrown ontof one side, by that time the opposite side is fullof steam, and will throw the pallet Lto the opposite side, and that sidewill iill.

By this arrangement, I save all the force for doing the work, and have adouble-acting boiler, so that when onev side is running, the oppositeside is filling, thus keeping up a steady, strong stream of water, andsteam pouring on to the clothes or vegetables, as the case may be.

Having thus fully described my invention, 1

What I claim as new, and desire to secure by Letters Patent, is

1. The reversed bottom, B, provided with a rim, C, projecting downwards,and said rim provided with openn ings, covered on the inside with valvesD D, substantially as and for the purposes herein set forth.

2. The removable cone-shaped tube E, secured to the reversed bottom, B,by means ofthe notched ange c ter extending up into' the tube E,substantially as and and keys (l d, or its equivalents, and provided atthe for the purposes herein set forth.
